Re: XP spontaneous close

Hello,

Please upload your file for a test if possible. I am interested.

?If you want that Mike takes care about your case, you have to send a bug report including the files to the email address given in the Help-About of the LTspice program.

Hello Mike,
Recently on XP SP3 LTSpice IV 4.321 I open a schematic with a .plt file and click run and LTSpice closes. Same with no .plt instead click a circuit node before the run has ended. It's ok if I let it run to the end. Tried re-installing, same. Time to move up to Vista? Just kidding.

Hello,

The very big Yahoo group "Tekscopes" started to move ?to?the group "Groups.io" in April. A very few weeks later they stopped the move and are now back to Yahoo. I am sure they will stay with Yahoo as long as possible.?That's the same what I will do. Stay as long as possible.?

Best regards,

Re: How about UCC25600 ? Re: course of HOWTO build models like (sanken) STR-A6100

#89877

Hello, :

I had been aware of that (TI) has a LLC product UCC25600. Is anyone interested in modeling behavior model of this ?

Or encrypted one ? Help the estimation of users' development ?

Those kind of simulation never gets high quality numerical quantities, but give the concept of the application behaviors.

Self modeling may involves imperfects, but it's just for fun.

Any opinion is appreciated.

Best regards.

The choice is very painful..

We can stay with Yahoo groups and roll with the punches..

Based on Verizon and how it dealt with AOL, I suspect that in a year or two Yahoo groups will loose ? even the paltry support it has..

I am a member of some Google groups; Google is autocratic in its changes; but usually they post a workaround...

I am not partial to Google groups; Any group forum alternative would be acceptable.

Bottom line:

Verixon bought Yahoo---->AOL is a good case study of ?what they did...

ADI bought LTC------>Aquisition of PMI is a good lesson...

The very future of this group is threatened.. Let us not seek solace in the status quo..

Let us not jump into an unknown fire either...

Hello Helmut,

V1 1 0 pulse(0 1 0 1u 1u .5m 1m)
R1 2 0 1.5k
*R2 2 0 1g
.machine
.output (2) V(1) < .5
.endmachine
.tran 3m

If I run the above netlist, it only produces 1mV on node 2, but the error log shows why:

WARNING: Less than two connections to node 1.? This node is used by V1.
WARNING: Less than two connections to node 2 of instance R1:? Node and device optimized out.

If I un-comment R2, then it produces 1.5V on node 2.? This is unexpected.? Using the netlist exactly as shown in the Help file does not produce 1V as expected (at least for me).

Your netlist shown below works as expected.

Hello Philippe

> See the help with keyword "state" ?[ .MACHINE -- Arbitrary State Machine ] in LTspice XVII

The Wine chm viewer doesn't allow search, I just installed xchm and, sure enough, there it is. Thanks for letting me know.

> The above netlist produces only 1mV on node 2.? However, if I add a 0V voltage source in series with R1, it produces 1V on node 2.? Very strange.

Hello analogspiceman, I just tried this new feature and it seems to go by the book to me (both examples from the help). Could it matter that I run the x64 version in Wine?

Hello Helmut,

Just to be sure I just reinstalled the new LTspice from their website.? I am running Windows 7 Home Premium 64 bit I-7.

R1 2 0 1k
.machine
.output (2) V(1) < .5
.endmachine

? ?"Google groups seems to allow file postings and file sharing..."

I have read many negative things about Google Groups.? I thought they eliminated the file storage/sharing capability, a couple of years ago?

I subscribe to a number of Google Groups too.? And I remember being sent some administrative messages from Google about the fact that they were about to delete those groups' file storage areas, and that this was our last chance to download them before they were removed from the Group.

In my view, Google Groups are not a good alternative to Yahoo!Groups.? Believe it or not, Yahoo!Groups, in spite of all the bugs and all the unwelcome changes and the wrenches they keep throwing into the mechanism, seems to be more stable than Google Groups.? Google happily changes and eliminates functions in their software products without regard for the effects on their user base.? I have seen groups that migrated from Yahoo to Google, then years later scooted back over to Yahoo after what Google did to them.

Hello Philippe

> "(it's unclear to me what that "p" means in A's formula, maybe 2 misspelled? "
> Isn't it pi ?

Wine displays it as the lower case letter "p", and so does xchm. I'd rather not speculate, though "2" would seem more appropiate in the context of A=ln()/2, B=ln()/2 => exp{ [ ln()*atan()+ln() ] / 2 }.

I must admit to being pleased that asking my pre-release version to do a sync release has resulted in the download of 30-something megabytes and it now reports as the full release.

?I think this was mentioned before.? Although a version of Wine might emulate only up to Windows XP, it is not Windows XP itself, and it might have many more "hooks" and low-level capabilities than an authentic MS-Windows XP has.? A direct comparison would not be fair.

Greetings..

Google groups seems to allow file postings and file sharing...

It may be a good idea , given Verizon's track record to get something going in Google groups..

Your thoughts?

Re: Is direct contact okay?

#89862

One can make a reasonable guess about the CT core dimensions from the data sheet, but it is not clear what the material is.? High quality CTs use tape-wound nickel-iron cores to keep magnetizing current to a minimum, but your CT has a split core, which probably introduces enough of an air gap that they might use ordinary transformer steel, since it is less expensive and magnetizing current would be dominated by the gap.? However, the difference still matters because you care about saturation and nickel-iron has only about half the saturation level of regular transformer steel (the core losses are lower, too).

It is easy to guess your application, you are most likely using MOSFETs to time multiplex the output of the CT between normal current sensing and supplying power for the current sense circuitry.? No doubt you are wondering how the build up of magnetizing current will affect the accuracy of the sensed signal and how much power you get with a relatively low duty cycle in power mode.
